Every so often we offer a promotion for free aquariums. These aquariums are from people upgrading, downgrading, repossesed, and previously rented. These aquariums are on a first come first served basis. These free aquariums are offered with our one year maintenance(11-12 servicing) agreement. The only thing other than a minimum $50/mo service fee is fish, new decor, or if a bulb or pump etc. if ever needed replacement. You can get these things anytime during the agreement from us or other. So Enjoy!
